Abstract
The landslide at K412 section of Shiyan-Tianshui Highway is an oldaged eolluvial landslide and the road passes right before it. As the excavation height was increased, the oldaged landslide underwent a revival locally to the extent increased gradually, and it may reactivate as a whole finally. Therefore, to known the spatial shape, the body structure, groundwater and other factors affecting the landslide must be checked; at the same time, with the deformation characteristics and some prospecting methods, such as probe drilling, geophysical exploration, deep-hole displacement monitoring, the landslide stability is analyzed comprehensively. As a result, the current safety margins of aged and reactivated landslide are established and rational advices on the treatment design thereof are proposed.关键词
